The depth specific significiance, relative abundance and phylogeography of anaerobic ammonium oxidation (anammox) in marine and estuarine sediments

open access: yes, 2009
PhDThe availability of fixed forms of nitrogen is critical to the regulation of primary production. Until recently, denitrification (the sequential reduction of NO3 -, through NO2 - , to di-nitrogen gas) was recognised as the only significant pathway

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

open access: yesAdvanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

First-stage and single-stage continuously stirred tank anaerobic digestion of synthetic complex wastewater and piggery wastewater (with emphasis on thermophilic temperature)

open access: yes, 2010
Single-stage continuously stirred tank reactor (CSTR) is commonly used in the anaerobic treatment of animal manure slurry, municipal sewage sludge and concentrated wastewaters containing a high proportion of biodegradable particulate organic materials at

Allosteric DNAzyme‐Enabled Sensitive and Multiplex Detection of Biomarkers for Rapid Diagnosis of Urinary Tract Infections

open access: yesAdvanced Science, EarlyView.
A catalytic allosteric DNAzyme assay (SMART) is developed by engineering DNAzyme into a unimolecular biosensor, enabling highly sensitive and multiplex detection of small molecules and nucleic acids. SMART enables extraction‐free, one‐pot, one‐step, isothermal, and cost‐effective detection of biological markers, achieving >95% accuracy for rapid ...

Microbial aspects of anaerobic methane oxidation with sulfate as electron acceptor

open access: yes, 2009
Anaerobic oxidation of methane (AOM) is an important methane sink in the ocean but the microbes responsible for AOM are as yet resilient to cultivation.

Feedstocks influence on the process parameters and the microbial community in anaerobic digestion [PDF]

open access: yes, 2013
To improve our understanding into the key parameters controlling and regulating the microbial groups involved in the anaerobic digestion (AD) process, particularly over multiple changes in operational conditions, triplicate lab-scale digesters fed with

Syntrophic growth on formate: a new microbial niche in anoxic environments

open access: yes, 2008
Anaerobic syntrophic associations of fermentative bacteria and methanogenic archaea operate at the thermodynamic limits of life. The interspecies transfer of electrons from formate or hydrogen as a substrate for the methanogens is key.

H2S‐Amplified “Three‐in‐One” Antibacterial Strategy for Periodontitis Treatment Using a Photosensitive Pillararene‐Embedded COF/MOF Hybrid

open access: yesAdvanced Science, EarlyView.
The integration of ROS‐generating systems with H2S depletion strategies effectively overcomes the limitations imposed by endogenous antioxidant defenses on ROS‐based antimicrobial therapies. In this study, the Cu‐MOF is incorporated into pillararene‐embedded COF, achieving a “three‐in‐one” antimicrobial effect that markedly alleviated periodontal ...

Methane emission and consumption at a Noth Sea gas seep (Tommeliten area) [PDF]

open access: yes, 2005
The Tommeliten seepage area is part of the Greater Ekofisk area, which is situated above the Tommeliten Delta salt diapir in the central North Sea (56°29.90' N, 2°59.80' E, Norwegian Block 1/9, 75 m water depth).

Treatment of domestic wastewater in an up-flow anaerobic sludge blanket reactor followed by moving bed biofilm reactor

open access: yes, 2010
The performance of a laboratory-scale sewage treatment system composed of an up-flow anaerobic sludge blanket (UASB) reactor and a moving bed biofilm reactor (MBBR) at a temperature of (22-35 A degrees C) was evaluated.
